As public school students across the city returned for in-person learning on Monday, Mayor Bill de Blasio said it will go down in history, calling it a "recovery day" for New York City.

The mayor visited P.S. 25 in the Bronx as kids made their return.But the day was not completely without some hiccups, according to parents at P.S. 81. 

The parents in Riverdale say their kids had to line up around the school and stand there for over 20 minutes in the morning, added to some of the stress of the big day for some kids.But by this afternoon's pickup time, the jitters appeared to have been replaced by excitement.

"It is time for the kids to be back in school, so we were happy. But it was definitely busy in the morning. The long line to get into the building," says Jennifer Herencia, the parent of a first grader at P.S. 81. "And they have to wear a mask and it's a long day and it's hot. But we're happy. The kids need it. They need to socialize and they need to be among their friends and their teachers."

News 12 spoke to several kids from P.S. 81 who said they felt safe wearing a mask and sitting 3 feet apart.
